LETTER-FILE.

To cir/ZZ whom t may concern:

Be it known that L-ALEXANDER DOM, a `citiy. zen of the United States, 'residingat Hartwell, in the county of Hamilton and State of Ohio, have invented certain new and useful Im provements in Letter-Files, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication.

My invention relatesto improvements in permanent and temporary files, usually in a transverse section in end elevation of a comi` pleted file embodying my invention. Fig. 2 is a plan `view of a portion of `the backof the file with the holders attached and the pin partly removed. Fig. 3 is a perspective view of the part ot the back with the holders attached and the pin entirely removed. Fig. 4 is a perspective View of a pair of holders, showing the pin in locked position therewith.

The same letters of reference are used to indicate identical parts in all the figures.

The tiling-case A is of the usual or any suitable construction, preferably in book form,

with a rounded back B, hinged lid C, and

hinged front iiap D. Before applying the,

covers C E to the back B, which is preferably mortised or gained to receive them, as seen at a, I apply the pin-holders F, which are looped Wires with their rear ends bent to form tan gs, (see Figs. land 4,) which are embedded in the back B and are covered bythe covers C E when the latter are fastened to the back, thus leaving the pin-holders projecting Within the ling-case, as Yshown particularly in Fig. l. Any number of ,pairs of these pin.- holders may be employed, those of each pair being arranged vertically opposite each other, as seen in Figs. 3 and 4, and for the purposes of my invention one pair for each case is found sufficient, and they are located at the middle'of the back B-that is to say', at the middle of the length of said back. The for- Ward endsof the pin-holders are broughttogether and formed into a contracted portion c, as seen in Figs. 2,' 3, and. 4.

Y The indexsheets G, such as are used in files of this character, have rearwardly-extending perforated ears d, Eig. l, through which are strung a pin or ordinary wire nail H, having aA head c at one end and a bent portion fat the opposite end.

When the index-sheets G are strung upon the pin, as seen in Fig. l, the latter has its lower bent endfrst inserted between the side arms of the lower holder E and is then pressed outward, when it is caught and retained in the contracted portion c by the spring action of the holder, the parts being represented at this stage by the dotted lines of Fig. l. The upper end of the pin is then drawn forward until its head e is pressed into the contracted portion c of the upper -holder F, Where it is held by the spring actionof the holder, and thus the piu, together with the index-sheets strung upon it, is held securely in place Within the le, and the file is usedin the ordinary manner forA the insertion of letters between the index-sheets.

It the holders F are not made of springwire, it is only necessary after the pin has been inserted toits proper'place in said holders to take a pair of pliers or other suitable tool and pinch the wires together behind the pin to prevent its accidental removal, as will be readily understood.

The above construction and method of application form a very simple and secure fastoning for the filing pin or pins, which cannot be accidentally displaced and which aerd a secure fastening for the index-sheets.

Having thus fully described my invention, I claim- Y l 1. Ina letter tile or binder, the combination with a back piece and a filing-pin, of a pair of wire loops having their ends secured to said back piece, and having contracted portions at their looped ends adapted to frictionallyengage and secure the opposite ends of said pin. 4

2. In a letter ile orN binder the combination With a back piece and, filing-pins, of a plurality of` pairs of wire loops having their IOO ends secured to said back piece, and having contracted portions at their looped ends adapted to frictionally engage and secure the opposite ends of said pins.

i 5 3. In a letter' le or binder the combination with a, back pieoe and a. ling-pin, of spring-wire' loops having their ends secured to said back piece and the looped portions adapted to frictionally engage nd-secure the xo opposite ends of said pin.

4. In a. letter file or binder the combina- Witnesses:
